+## Configuring Environment
+
+Source the `setup-env.sh` script to prefix the `PATH`, `LD_LIBRARY_PATH`, etc. environment variables:
+
+```bash
+source /opt/omnitrace/share/omnitrace/setup-env.sh
+```
+
+Alternatively, if environment modules are supported, add the `<prefix>/share/modulefiles` directory to `MODULEPATH` via:
+
+```bash
+module use /opt/omnitrace/share/modulefiles
+```
+
+> ***Alternatively, the above line can be added to the `${HOME}/.modulerc` file.***
+
+Once omnitrace is in the `MODULEPATH`, omnitrace can be loaded via `module load omnitrace/<VERSION>` and unloaded via `module unload omnitrace/<VERSION>`, e.g.:
+
+
+```bash
+module load omnitrace/1.0.0
+module unload omnitrace/1.0.0
+```
+
+> ***You may need to also add the path to the ROCm libraries to `LD_LIBRARY_PATH`, e.g. `export LD_LIBRARY_PATH=/opt/rocm/lib:${LD_LIBRARY_PATH}`***
+
+### Validating Environment Configuration
+
+If all the following commands execute successfully with output, then you are ready to use omnitrace:
+
+```bash
+which omnitrace
+which omnitrace-avail
+omnitrace --help
+omnitrace-avail --all
+```
